Subject: [GIT PULL] nohz: Updates for 4.3

Ingo,

Please pull the timers/nohz-for-tip branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	timers/nohz-for-tip

HEAD: de734f89b67c2df30e35a09e7e56a3659e5b6ac6

--
Summary of changes:

* Fix some jiffies based cputime assumptions. No real harm because the
  concerned code isn't used by full dynticks.

* Simplify jiffies <-> usecs conversions. Remove dead code.

* Remove early hacks on nohz full code that avoided messing up idle
  nohz internals. Now nohz integrates well full and idle and such hack
  have become needless.

* Restart nohz full tick from irq exit. A simplification and a
  preparation for future optimization on scheduler kick to nohz full.

* Simple code cleanups.

* Tile driver isolation enhancement on top of nohz.

Thanks,
	Frederic
